Abstract (en)
[origin: WO2011128798A1] A system and method control an amount of power delivered by a power converter (220) to a solid state lighting load (240). It is determined whether a dimmer (204) is present between a voltage source (201) and the power converter (220) based on a rectified input voltage from the voltage source. When the dimmer is determined to be present, an operating point of the power converter is adjusted to increase the amount of power delivered by the power converter to the solid state lighting load by a compensation amount, so that the increased amount of power is equal to an amount of power delivered by the power converter when the dimmer is not present.
